The Prime series is a highly reliable contactless card chip introduced by LEGIC in 1992. So far, the chip has not been cracked, and there is no compatible chip. It can be seen that the security of its products is high. The commonly used models of the Prime series include LEGIC MIM256 and LEGIC MIM1024. The products are widely used in security fields such as access control and identification, and occupy a leading position in the access security market in Europe.
